Add libdw-based functions for loading and querying debuginfo. Load debuginfo from the system and the linux-user loaders. This is useful for the upcoming perf support, which can then put human-readable guest symbols instead of raw guest PCs into perfmap and jitdump files.

Hi,I recently did a build with "configure --without-default-features" and I noticed that this new libdw does not get disabled automatically there, which looks kind of weird. Is there a reason that there is no config knob here to disable it like we have it with all the other optional libraries that we support?
